I have been following this thread with great interest. Here are my 4 cents. We have a webmail setup as follows:
Dual AMD Athlon MP 2400 w/ 1 GB RAM RAID 5 (3 ATA133 7200 RPM disks with 8MB cache) Adaptec 2400 ATA RAID controller Linksys Gigabit NIC (gigabit uplink to router ;-)) FreeBSD 4.10 Squirrelmail 1.4.3a (options to use server sort etc). Apache 2_0_52,3 w/ modssl PHP 4.3.9 (increased memory & execution times in php.ini) Turck-mmcache 2.4.6 Courier IMAP 3.0.8,1 w/ server-side sorting Postfix 2.1.5,1 (maildir option) Vexira anti-virus I am not using LDAP, MySQL etc. We have external SPAM filtering, and I also do not have that many users - 250 in all and only a fraction of them using SM. This same setup was also on a dual PIII 1.1GHZ system. In both cases I experienced the same issues as the original author of this thread: CPU load jumps to 99% during initial login (blew my argument for the AMD system out of the water!) After that initial login, the system is fine. This happens on accounts that have many folders and subfolders. Interesting thing is I have done almost all the suggestions that have been made in this thread, I am using top-notch hardware (although not the best money can buy), and still experiencing the same issue, but with far fewer users than other setups. Since we have so few SM users it's not a big deal, the biggest CPU hog being myself ;-) but I can see where this would be a critical (read SM rejecting) issue when more users come on. I have also looked into IMAP alternatives but the one that seems most promising - Dovecot - isn't ready for production use yet. For what it's worth, I think this is an SM issue because using other IMAP clients - Thunderbird, Evolution, Eudora, Outlook, etc. do not cause the jump in CPU load - at least not on my server.
